Description

Technical Field

[0001] This utility model relates to the technical field of tire production, and in particular to a rolling device for an aircraft tire tread winding machine. Background Technology

[0002] In the production process of aircraft tires, in order to improve the strength of aircraft tires, a layer of rubber strip containing reinforcing fibers or steel wires is usually wound onto the tread layer. When winding the rubber strip onto the tread, an adhesive is first applied to the tread, and then the rubber strip is wound around the tread, so that the rubber strip is fixed to the tread by the adhesive. Then, the rubber strip on the tread is squeezed by a rolling device to squeeze out the air bubbles in the rubber layer between the rubber strip and the tread, ensuring that the rubber strip can be tightly attached to the tire body, thereby improving the bonding strength between the tread and the rubber strip. In the prior art, utility model patent with patent application number 201610684222.9 discloses a rolling mechanism for a tire tread winding machine, which is mainly composed of pressure rollers. When rolling the tire tread, the tire body with rubber strips wrapped around it is first fixed, and then the rubber strips are rolled by the pressure rollers to make the rubber strips adhere more tightly to the tire body, while removing air bubbles in the rubber layer between the rubber strips and the tire body. However, it has the following problems in use: it only removes air bubbles in the rubber layer by rolling, which is not very effective in removing air bubbles, is inconvenient to use, and has poor practicality. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a rolling device for an aviation tire tread winding machine that promotes the removal of air bubbles in the rubber layer on the tire surface through a dual method of rolling and vacuuming, resulting in better air bubble removal, ease of use, and high reliability and practicality.

[0004] This utility model discloses a rolling device for an aircraft tire tread winding machine, comprising a base plate, a fixing mechanism, a vacuum mechanism, and a rolling mechanism. The fixing mechanism is mounted on the base plate and is used to fix the tire body. The vacuum mechanism is mounted on the base plate and has a vacuuming function. The rolling mechanism has a rolling function. First, the tire body with rubber strips wound around it is fixed by the fixing mechanism. Then, the tire body is placed in a negative pressure environment to promote the escape of air bubbles in the rubber layer on the surface of the tire body. At the same time, the rolling mechanism rolls the rubber strips on the surface of the tire body, making the rubber strips adhere more tightly to the tire body. It promotes the expulsion of air bubbles in the rubber layer on the surface of the tire body through the dual methods of rolling and vacuuming, resulting in better air bubble removal. It is convenient to use and has high reliability and practicality.

[0005] Preferably, the vacuum mechanism includes a support, a housing, a vacuum pump, and a sealing mechanism. The support is fixedly mounted on a base plate, and the housing is fixedly mounted on the upper end of the support. A chamber is provided inside the housing, and the right end of the housing is set as an opening. The vacuum pump is mounted on the housing, and the input end of the vacuum pump is connected to the chamber of the housing. The sealing mechanism is used to seal the opening at the right end of the housing. When rolling the tire carcass, the tire carcass is placed in the housing, and the opening at the right end of the housing is sealed by the sealing mechanism. Then, the vacuum pump is turned on, so that the chamber of the housing is in a negative pressure state, so that the tire carcass is in a negative pressure environment, which promotes the escape of air bubbles in the rubber layer on the surface of the tire carcass. At the same time, the rolling mechanism rolls the surface of the tire carcass.

[0006] Preferably, the sealing mechanism includes a sealing plate and a moving mechanism. A sealing gasket is provided at the left end of the sealing plate. The sealing plate is located at the right end of the box. The sealing plate is mounted on the moving mechanism, which is used to move the sealing plate left and right. When sealing the right end of the box, the moving mechanism is opened, causing the sealing plate to move to the left. During the leftward movement, the sealing plate contacts the right end of the box, thereby sealing the chamber of the box and facilitating the sealing of the box.

[0007] Preferably, the moving mechanism includes a support, a hydraulic cylinder, a fixed plate, a push rod, and a sliding rod. The support is fixedly mounted on the base plate, the hydraulic cylinder is fixedly mounted on the support, the fixed plate is mounted on the support, and the power output end of the hydraulic cylinder is provided with a push rod. Both the push rod and the sliding rod are slidably mounted on the fixed plate. The sealing plate is fixedly mounted on the left end of the push rod and the sliding rod. When the sealing plate is moved left or right, the hydraulic cylinder is opened, and the hydraulic cylinder moves the sealing plate in the left and right directions through the push rod, thus facilitating the left and right movement of the sealing plate.

[0008] Preferably, the fixing mechanism includes a mounting frame, an indexing plate, a support shaft, a support, and a wheel rim. The indexing plate is fixedly mounted on the mounting frame, the support shaft is mounted on the rotating end of the right side of the indexing plate, the support shaft is rotatably mounted on the housing and the support, the support is fixedly mounted on the mounting frame, and the wheel rim is fixedly mounted on the right end of the support shaft. The wheel rim is located inside the cavity of the tire body. When fixing the tire body, the tire body is mounted on the wheel rim and fixed so that the tire body is located inside the cavity of the housing, which facilitates the fixing of the tire body.

[0009] Preferably, the rolling mechanism includes a servo cylinder A, a moving rod, a mounting frame, and a pressure roller. The servo cylinder A is fixedly mounted on the upper end of the bracket, the moving rod is slidably mounted on the housing, the power output end of the servo cylinder A is connected to the moving rod, the mounting frame is fixedly mounted on the front end of the moving rod, and the pressure roller is rotatably mounted on the mounting frame, located inside the housing. After the tire body is fixed by the rim, the servo cylinder A is opened, driving the moving rod, the mounting frame, and the pressure roller to move forward, so that the pressure roller contacts the rubber strip on the surface of the tire body. Pressure is applied to the rubber strip on the surface of the tire body by the pressure roller, and at the same time, the indexing plate causes the support shaft to drive the rim and the tire body to rotate. During the rotation, the tire body is rolled by the pressure roller on the rubber strip on the surface of the tire body, which improves the adhesion between the rubber strip and the tire body.

[0010] Preferably, it also includes a servo cylinder B, a lifting rod, and a scraper. The power end of the servo cylinder B is equipped with a lifting rod, which is slidably mounted on the bracket and the housing. The scraper is mounted on the upper end of the lifting rod and is located below the pressure roller. When the pressure roller rolls the rubber strip on the surface of the tire body, the escaping rubber layer may sometimes adhere to the surface of the pressure roller. When cleaning the surface of the pressure roller, the servo cylinder B is turned on, and the servo cylinder B raises the scraper through the lifting rod, thereby making the scraper contact the surface of the pressure roller. When the tire body rotates, the tire body drives the pressure roller to rotate, and the scraper scrapes off the rubber layer on the surface of the rotating pressure roller, which facilitates the cleaning of the scraper.

[0011] Compared with the prior art, the advantages of this utility model are: by using a dual method of rolling and vacuuming, the air bubbles in the rubber layer on the surface of the tire carcass are promoted to be expelled, the effect of expelling air bubbles is better, it is convenient to use, and has high reliability and practicality.

Then, the vacuum pump 4 is turned on, so that the chamber of the housing 3 is in a negative pressure state, so that the tire body 23 is in a negative pressure environment, which promotes the escape of air bubbles in the rubber layer on the surface of the tire body 23. At the same time, the rolling mechanism rolls the surface of the tire body 23.

[0017] like Figure 1 The sealing mechanism includes a sealing plate 5 and a moving mechanism. A sealing gasket is provided at the left end of the sealing plate 5.
